    Klarnetin staccato tekniğini güçlendirme aşamaları eser çalışmalarıyla uygulanmıştır. Staccato geçişlerini hızlandıracak ritim ve nüans çalışmalarına yer verilmiştir. Çalışmanın en önemli amacı sadece staccato çalışması değil parmak-dilin eş zamanlı uyumunun hassasiyeti üzerinde de durulmasıdır. Staccato çalışmalarını daha verimli hale getirmek için eser çalışmasının içinde etüt çalışmasına da yer verilmiştir. Çalışmaların üzerinde titizlikle durulması staccato çalışmasının ilham verici etkisi ile müzikal kimliğe yeni bir boyut kazandırmıştır. Sekiz özgün eser çalışmasının her aşaması anlatılmıştır. Her aşamanın bir sonraki performans ve tekniği güçlendirmesi esas alınmıştır. Bu çalışmada staccato tekniğinin hangi alanlarda kullanıldığı, nasıl sonuçlar elde edildiği bilgisine yer verilmiştir. Notaların parmak ve dil uyumu ile nasıl şekilleneceği ve nasıl bir çalışma disiplini içinde gerçekleşeceği planlanmıştır. Kamış-nota-diyafram-parmak-dil-nüans ve disiplin kavramlarının staccato tekniğinde ayrılmaz bir bütün olduğu saptanmıştır. Araştırmada literatür taraması yapılarak staccato ile ilgili çalışmalar taranmıştır. Tarama sonucunda klarnet tekniğin de kullanılan staccato eser çalışmasının az olduğu tespit edilmiştir. Metot taramasında da etüt çalışmasının daha çok olduğu saptanmıştır. Böylelikle klarnetin staccato tekniğini hızlandırma ve güçlendirme çalışmaları sunulmuştur. Staccato etüt çalışmaları yapılırken, araya eser çalışmasının girmesi beyni rahatlattığı ve istekliliği daha arttırdığı gözlemlenmiştir. Staccato çalışmasını yaparken doğru bir kamış seçimi üzerinde de durulmuştur. Staccato tekniğini doğru çalışmak için doğru bir kamışın dil hızını arttırdığı saptanmıştır. Doğru bir kamış seçimi kamıştan rahat ses çıkmasına bağlıdır. Kamış, dil atma gücünü vermiyorsa daha doğru bir kamış seçiminin yapılması gerekliliği vurgulanmıştır. Staccato çalışmalarında baştan sona bir eseri yorumlamak zor olabilir. Bu açıdan çalışma, verilen müzikal nüanslara uymanın, dil atış performansını rahatlattığını ortaya koymuştur. Gelecek nesillere edinilen bilgi ve birikimlerin aktarılması ve geliştirici olması teşvik edilmiştir. Çıkacak eserlerin nasıl çözüleceği, staccato tekniğinin nasıl üstesinden gelinebileceği anlatılmıştır. Staccato tekniğinin daha kısa sürede çözüme kavuşturulması amaç edinilmiştir. Parmakların yerlerini öğrettiğimiz kadar belleğimize de çalışmaların kaydedilmesi önemlidir. Gösterilen azmin ve sabrın sonucu olarak ortaya çıkan yapıt başarıyı daha da yukarı seviyelere çıkaracaktır

    Since its inception, fluorescence microscopy has been a key source of discoveries in cell biology. Advancements in fluorophores, labeling techniques and instrumentation have made fluorescence microscopy a versatile quantitative tool for studying dynamic processes and interactions both in vitro and in live-cells. In this thesis, I apply quantitative fluorescence microscopy techniques in live-cell environments to investigate several biological processes. To study Gag processing in HIV-1 particles, fluorescence lifetime imaging microscopy and single particle tracking are combined to follow nascent HIV-1 virus particles during assembly and release on the plasma membrane of living cells. Proteolytic release of eCFP embedded in the Gag lattice of immature HIV-1 virus particles results in a characteristic increase in its fluorescence lifetime. Gag processing and rearrangement can be detected in individual virus particles using this approach. In another project, a robust method for quantifying Förster resonance energy transfer in live-cells is developed to allow direct comparison of live-cell FRET experiments between laboratories. Finally, I apply image fluctuation spectroscopy to study protein behavior in a variety of cellular environments. Image cross-correlation spectroscopy is used to study the oligomerization of CXCR4, a G-protein coupled receptor on the plasma membrane. With raster image correlation spectroscopy, I measure the diffusion of histones in the nucleoplasm and heterochromatin domains of the nuclei of early mouse embryos. The lower diffusion coefficient of histones in the heterochromatin domain supports the conclusion that heterochromatin forms a liquid phase-separated domain. The wide range of topics covered in this thesis demonstrate that fluorescence microscopy is more than just an imaging tool but also a powerful instrument for the quantification and elucidation of dynamic cellular processes

    Queer spies in British Cold War culture: literature, film, theatre and television

    This PhD thesis investigates how male homosexuality has been represented in British spy fiction from the 1950s to the 2010s in multiple media: literature, film, television and theatre. Due mainly to the betrayal of the Cambridge Spy ring around the middle of the century, British culture has associated spies with homosexuality, while the wider Anglophone world was in the grip of a homophobic atmosphere created by McCarthy's Red Scare. My thesis explores how this history is reflected in the spy genre from the Cold War to the present, in which male homosexuality and secret agency intersect as “queer”, in so far as they were both considered to be discreet and criminal, existing outside of the heteronormative order. By following multiple texts across media and time, I discuss how some writers, television and film directors and actors update queer identity in spy fiction, creating a shifting image of queer spies through decades. I refer to the findings of adaptation studies and queer studies, along with numerous studies on spy fiction. I conclude that the interrelation of different media has contributed to the re-drawing of queer identity in spy fiction. These developments have enabled the spies' queer identity to transcend its pejorative history in British culture, towards its more flexible and pliant sense which is designated by the term's modern usage. I also discuss that spies’ homosexuality has been represented as a fleeting ghost in most of the texts examined, hovering on the margins of pages and screen. Although homosexuality is not “the love that dare not speak its name” anymore, clandestine queer spies have been preserved as spectral others in the genre for many years. Spy fiction is a cultural repository retaining the memory of violence inflicted against those who have been called “queer” in twentieth century Britain, and the spectral nature of queer spies narrates this history reaching back to the Oscar Wilde trial in 1895, from which point British queer identity as we know now developed. This thesis benefits the study of spy fiction by filling a gap in the investigation of homosexual representation. It also contributes to the field of gender studies of literature, film, television, and theatre by illustrating queer history in a genre which has not received a great deal of focus on its representation of homosexuality. Spy fiction occupies a central position in British popular culture, and by exploring this genre in terms of homosexuality, this research will identify the role which same-sex desire has historically played in the British cultural imagination

    Interference mitigation in LiFi networks

    Due to the increasing demand for wireless data, the radio frequency (RF) spectrum has become a very limited resource. Alternative approaches are under investigation to support the future growth in data traffic and next-generation high-speed wireless communication systems. Techniques such as massive multiple-input multiple-output (MIMO), millimeter wave (mmWave) communications and light-fidelity (LiFi) are being explored. Among these technologies, LiFi is a novel bi-directional, high-speed and fully networked wireless communication technology. However, inter-cell interference (ICI) can significantly restrict the system performance of LiFi attocell networks. This thesis focuses on interference mitigation in LiFi attocell networks. The angle diversity receiver (ADR) is one solution to address the issue of ICI as well as frequency reuse in LiFi attocell networks. With the property of high concentration gain and narrow field of view (FOV), the ADR is very beneficial for interference mitigation. However, the optimum structure of the ADR has not been investigated. This motivates us to propose the optimum structures for the ADRs in order to fully exploit the performance gain. The impact of random device orientation and diffuse link signal propagation are taken into consideration. The performance comparison between the select best combining (SBC) and maximum ratio combining (MRC) is carried out under different noise levels. In addition, the double source (DS) system, where each LiFi access point (AP) consists of two sources transmitting the same information signals but with opposite polarity, is proven to outperform the single source (SS) system under certain conditions. Then, to overcome issues around ICI, random device orientation and link blockage, hybrid LiFi/WiFi networks (HLWNs) are considered. In this thesis, dynamic load balancing (LB) considering handover in HLWNs is studied. The orientation-based random waypoint (ORWP) mobility model is considered to provide a more realistic framework to evaluate the performance of HLWNs. Based on the low-pass filtering effect of the LiFi channel, we firstly propose an orthogonal frequency division multiple access (OFDMA)-based resource allocation (RA) method in LiFi systems. Also, an enhanced evolutionary game theory (EGT)-based LB scheme with handover in HLWNs is proposed. Finally, due to the characteristic of high directivity and narrow beams, a vertical-cavity surface-emitting laser (VCSEL) array transmission system has been proposed to mitigate ICI. In order to support mobile users, two beam activation methods are proposed. The beam activation based on the corner-cube retroreflector (CCR) can achieve low power consumption and almost-zero delay, allowing real-time beam activation for high-speed users. The mechanism based on the omnidirectional transmitter (ODTx) is suitable for low-speed users and very robust to random orientation

    Hunting Wildlife in the Tropics and Subtropics

    Get PDF
    The hunting of wild animals for their meat has been a crucial activity in the evolution of humans. It continues to be an essential source of food and a generator of income for millions of Indigenous and rural communities worldwide. Conservationists rightly fear that excessive hunting of many animal species will cause their demise, as has already happened throughout the Anthropocene. Many species of large mammals and birds have been decimated or annihilated due to overhunting by humans. If such pressures continue, many other species will meet the same fate. Equally, if the use of wildlife resources is to continue by those who depend on it, sustainable practices must be implemented. These communities need to remain or become custodians of the wildlife resources within their lands, for their own well-being as well as for biodiversity in general.

    Platform protocol place: a practice-based study of critical media art practice (2007-2020)

    Get PDF
    This practice-based research project focuses on critical media art practices in contemporary digital culture. The theoretical framework employed in this inquiry draws from the work of the Frankfurt School, in particular Theodor Adorno and Max Horkheimer’s The Culture Industry: Enlightenment as Mass Deception. Using Adorno & Horkheimer’s thesis as a theoretical guide, this research project formulates the concept of the digital culture industry - a concept that refers to the contemporary era of networked capitalism, an era defined by the unprecedented extraction, accumulation and manipulation of data and the material and digital infrastructures that facilitate it. This concept is used as a framing mechanism that articulates certain techno-political concerns within networked capitalism and responds to them through practice. The second concept formulated within this research project is Platform Protocol Place. The function of this second concept is to frame and outline the body of practice-based work developed in this study. It is also used to make complex technological issues accessible and to communicate these issues through public exhibition and within this written thesis. The final concept developed in this research project is tactical media archaeology. This concept describes the techniques and approaches employed in the development of the body of practice-based work that are the central focus of this research project. This approach is a synthesis of two subfields of media art practice and theory, tactical media and media archaeology. Through practice, tactical media archaeology critiques the geopolitical machinations and systems beneath the networked devices and interfaces of the digital culture industry
